Generalized Riemann zeta function

5

Is the "generalized Riemann zeta function" `zeta(s,a)` also implemented? The generalized Riemann zeta function is identical to the hurwitz zeta function for `Re(a)>0` for `Re(a)

`UnderflowException` should be thrown instead of an OverflowException?

3

An `UnderflowException` should be thrown instead of a `OverflowException`? Example: ```mma N(Erfc(100000000000000000000000000000000035/2*1/Sqrt(2)),30) ```

hyperGeometricU - is it possible to get -Infinity, Infinity as a result?

5

Example: ``` hypergeometricU(3.0, 1.0, 0.0); ``` Should return `Infinity` Can we have some special values for this case or a specialized exception? Same for "ArithmeticException" with "Division by zero" text?

Is hypergeometricPFQ somewhere public available?

5

Is the `hypergeometricPFQ` method also already available for calls from outside `apfloat` library? - https://github.com/mtommila/apfloat/blob/6e3088cd70dcc873e6df004f9646702570f24626/apfloat/src/main/java/org/apfloat/HypergeometricHelper.java#L447 `HypergeometricHelper` is package private.

Support for Mathematica input syntax

1

Can you please add support for Mathematica input syntax: - https://reference.wolfram.com/language/tutorial/InputSyntax.html#7977 maybe not as constructor like here to avoid incompatibilties: - https://github.com/mtommila/apfloat/blob/ca0384d4deb8e88c4d10bb8984fa45cfddda7e1b/apfloat/src/main/java/org/apfloat/Apfloat.java#L116 but in a static "valueOf...()" method?

Full support for Tetrahedron, Dodecahedron Icosahedron, Octahedron, Polyhedron

17

Can you add full support for `Cylinder, Tetrahedron, Dodecahedron, Icosahedron, Octahedron, Polyhedron, ...`? Or describe a way for getting this things displayed with some preprocessing steps?

Please add legends for complex parametric plots with colours and their corresponding values. Example: ``` function z1(z) { try { return inverseHaversine(z);}catch(e){return complex(Number.NaN);} } var p1 = parametric( (re,im) =>...

More "adaptive" plot function?

2

Can we get a more "adaptive" plot function? See for example these discussions: - https://scicomp.stackexchange.com/questions/2377/algorithms-for-adaptive-function-plotting - https://github.com/JuliaPlots/Plots.jl/issues/621 Especially this function plot example will benefit from such an "adaptive" approach: ```...

Sorry I somehow missed #18. Can the formula: `HarmonicNumber(n) == EulerGamma + PolyGamma(0, 1 + n) ` be used in `harmonic` for non-integer arguments? https://github.com/paulmasson/math/blob/e8a5603a3157d0ff044b8126f3bca0d3c5bcad26/build/math.js#L4464 Also for 2 arguments: `HarmonicNumber(n,...

The following example should return `-0.5`: ```javascript console.log(hypergeometric2F1(-3.0,-1.0,-2.0,1.0)); ``` The following example should return appro: `5.513090059384266E23` ```javascript console.log(hypergeometric2F1(2,2,3.01,0.95)); ``` See tests: - https://github.com/kspalaiologos/Maja/blob/19381abbcfb4aca44871f050a9cac79d6f2a14f4/src/test/java/TestHypergeometric.java#L19C20-L19C36
